I had a guy call tonight stating he had some motherboards, fingercards and peripherals that he would like to sell to me. He also stated that he had a few catalyst converters that he had decanned himself for sale as well. I do not have any experience in dealing with converters and am a little skeptical about buying something that was decanned. I imagine it would be difficult to tell what kind of vehicle they came from without stamps. Any suggestions out there about what I should be looking for? Thanks guys and gals!
